Disgruntled British spy Richard Tomlinson charged last night that the man who drove Princess Diana’s death car was an informant for British intelligence.

Continuing his high-profile “exposure” of secret British intelligence operations, Tomlinson also charged that there was a plot by his former spy service to kill Yugoslav strongman Slobodan Milosevic.

Tomlinson was fired from Britain’s MI6 intelligence agency in 1995.

British authorities accuse him of posting on the Internet the names of more than 100 undercover agents for MI6 – in a crusade reminiscent of ex-CIA agent Philip Agee’s naming of CIA agents and operations in the 1970s.

Tomlinson made his allegations in an interview on Britain’s Channel Four, conducted in a Swiss Hotel.

He said he once saw a file with a code number of an MI6 informant at The Ritz hotel in Paris.

“It was the same person who was the chauffeur of the car at the time of Diana’s death, Henri Paul – he was a security officer and the Ritz’s MI6 source … MI6 never let a source drop,” he said.

Paul, as well as the former Princess of Wales and her companion, Dodi Fayed, were killed in the August 1997 car crash in Paris. Dodi’s father, Mohamed, owns The Ritz.

Tomlinson said a substantial amount of money had been put in Paul’s bank account.

“The obvious implication is that it came from MI6, so clearly MI6 … were in contact with him right until his death,” Tomlinson said.

On the plan to kill Milosevic, Tomlinson said he saw a three-page MI6 document that “outlined potential scenarios of how the killing could be done and the justification for doing it.”

Options included funding a bombing using opposition Serbian groups and sending elite units into Belgrade to “make it appear like a car accident.”

“It wasn’t a joke, it was a serious document. It still exists as it was an accountable document – it will still be in MI6 files,” he said.

Tomlinson’s sensational charges could not be confirmed last night, and there was no immediate comment from the British government.
